We have observed the steep spectrum radio source B2 0924+30 using the LOw Frequency ARray (LOFAR) telescope. Hosted by a z = 0.026 elliptical galaxy, it has a relatively large angular size of 12′ (corresponding to 360 kpc projected linear size) and a morphology reminiscent of a remnant Fanaroff-Riley type II (FRII) radio galaxy. Studying active galactic nuclei (AGN) radio remnants can give us insight into the time-scales involved into the episodic gas accretion by AGNs and their dependence on… Expand

Studying the late evolution of a radio-loud AGN in a galaxy group with LOFAR
Feedback by radio-loud active galactic nuclei (AGNs) in galaxy groups is not fully understood. Open questions include the duty cycle of the AGN, the spatial extent of the radio lobes, the effect theyExpand
Duty cycle of the radio galaxy B2 0258+35
Radio loud Active Galactic Nuclei are episodic in nature, cycling through periods of activity and quiescence. In this work we investigate the duty cycle of the radio galaxy B2~0258+35, which wasExpand
The best of both worlds: Combining LOFAR and Apertif to derive resolved radio spectral index images
Supermassive black holes at the centres of galaxies can cycle through periods of activity and quiescence. Characterising the duty cycle of active galactic nuclei is crucial for understanding theExpand
A study of spectral curvature in the radio relic in Abell 4038 using the uGMRT
The remnant radio galaxies in galaxy clusters are important sources of seed relativistic electron population in the intra-cluster medium (ICM). Their occurrence and spectral properties are poorlyExpand
J1615+5452: a remnant radio galaxy in the ELAIS-N1 field
We report the discovery of a remnant radio AGN J1615+5452 in the field of ELAIS-N1. GMRT continuum observations at 150, 325 and 610 MHz combined with archival data from the 1.4 GHz NVSS survey wereExpand
Remnant radio-loud AGN in the Herschel-ATLAS field
Only a small fraction of observed active galactic nuclei (AGN) display large-scale radio emission associated with jets, yet these radio-loud AGN have become increasingly important in models of galaxyExpand
Duty-cycle and energetics of remnant radio-loud AGN
Deriving the energetics of remnant and restarted active galactic nuclei (AGNs) is much more challenging than for active sources due to the complexity in accurately determining the time since theExpand
Spectral ageing in the era of big data: integrated versus resolved models
Continuous injection models of spectral ageing have long been used to determine the age of radio galaxies from their integrated spectrum; however, many questions about their reliability remainExpand
Archaeology of active galaxies across the electromagnetic spectrum
Analytical and numerical galaxy-formation models indicate that active galactic nuclei (AGNs) likely play a prominent role in the formation and evolution of galaxies. However, quantifying this effectExpand

LOFAR discovery of a 700-kpc remnant radio galaxy at low redshift
Remnant radio galaxies represent the final "dying" phase of radio galaxy evolution, in which the jets are no longer active. Due to their rarity in flux limited samples and the difficulty ofExpand
AGN duty cycle estimates for the ultra-steep spectrum radio relic VLSS J1431.8+1331
Context. Steep spectrum radio sources associated with active galactic nuclei (AGN) may contain remnants of past AGN activity episodes. Studying these sources gives us insight into the AGN activityExpand
Spectral ageing in the lobes of cluster-centre FR II radio galaxies
Recent investigations have shown that many parameters and assumptions made in the application of spectral ageing models to FR-II radio galaxies (e.g. injection index, uniform magnetic field,Expand
Episodic radio galaxies J0116−4722 and J1158+2621: can we constrain the quiescent phase of nuclear activity?
We present multifrequency radio observations of two well known episodic FR II radio galaxies (J0116 4722 and J1158+2621) and a detailed investigation of the life-cycle of epis odic radio galaxiesExpand
FR II radio galaxies at low frequencies – II. Spectral ageing and source dynamics
In this paper, the second in a series investigating FR II radio galaxies at low frequencies, we use LOFAR and VLA observations between 117 and 456 MHz in addition to archival data to determine theExpand
We have formed a new sample which consists of extended extragalactic radio sources without obvious active galactic nuclei (AGNs) in them. Most of these sources appear to be dead double radio sources.Expand
Wide-field LOFAR imaging of the field around the double-double radio galaxy B1834+620 A fresh view on a restarted AGN and doubeltjes
Context. The existence of double-double radio galaxies (DDRGs) is evidence for recurrent jet activity in AGN, as expected from standard accretion models. A detailed study of these rare sourcesExpand
FR II radio galaxies at low frequencies - I. Morphology, magnetic field strength and energetics.
The morphology of 3C 452 is that of a standard FR II rather than of a double-double radio galaxy as had previously been suggested, with no remnant emission being observed beyond the active lobes, and revised estimates of the internal pressures and magnetic field strengths for the intrinsically steep case are provided.
